Hybrid Tea rose plant named ‘Hadque’

ABSTRACT

A new and distinct hybrid tea rose cultivar named ‘Hadque’, particularly characterized by having stems without prickles; large yellow flowers which are lightly pink shaded; flowers borne singly and having strong fragrance; rapid repeat bloom, and the plant being bushy and upright.

Botanical/commercial classification: Rosa hybrida/Hybrid Tea Rose Plant.

BACKGROUND AND SUMMARY OF THE INVENTION

The present invention relates to a new and distinctive cultivar of rose plant of the Hybrid Tea class, which was originated by my crossing ‘KIKA’ as the seed parent with ‘REMEMBER ME’ as the pollen parent.

Among the novel characteristics possessed by the new cultivar which distinguish it from:

-   -   (a) All other cultivars of which I am aware are:         -   (1) Prickles being absent from any stems.         -   (2) Large yellow flower with light pink shading.         -   (3) Single flower to the stem.         -   (3) Strong fragrance.         -   (4) Very consistent free bloomer.     -   (b) Seed parent: White hybrid tea; typically in clusters of         three flowers; no prickles.

Pollen parent: Copper, red-orange, yellow hybrid tea; has prickles. Asexual reproduction of the new rose cultivar by budding onto the rootstock ‘Dr. Huey’, as performed at Vasco, Calif., shows that the aforementioned and all other distinctive characteristics come true to form and are established and transmitted through succeeding propagations. The cultivar name of this plant is ‘Hadque’. The plant is being marketed under the commercial name of ‘Smooth Queen’.

BRIEF DESCRIPTION OF THE DRAWING/PHOTOGRAPH

The accompanying photographic illustration/drawing shows typical specimens of the vegetative growth and flowers of the new cultivar in different stages of development and as depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.
